La demande du consommateur OAuth pour le jeton de ServiceProvider renvoie InternalServerError

Question

Je m'amuse avec DevDefined.OAuth - une implémentation consommateur et fournisseur OAuth pour .Net http://code.google.com/p/devdefined-tools/wiki/OAuth et lors du lancement du projet ExampleConsumerSite après la configuration des points de terminaison de service sur mon serveur Web IIS 7, je reçois le erreur suivante:

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Exception: Request for uri: http://localhost:8080/RequestToken.aspx?oauth_callback=oob&oauth_nonce=94efde0b-dd45-4cee-8253-7496cef0b877&oauth_consumer_key=key&oauth_signature_method=PLAINTEXT&oauth_timestamp=1252512419&oauth_version=1.0&oauth_token=&oauth_signature=secret%2526 failed.
status code: InternalServerError

J'ai remarqué que le paramètre oauth_token GET est vide. En traçant cela, la source d'erreur provient de la ligne 12 de la page Default.aspx.cs:

IToken requestToken = session.GetRequestToken();

protected void oauthRequest_Click(object sender, EventArgs e)
{
  OAuthSession session = CreateSession();

  IToken requestToken = session.GetRequestToken();

  if (string.IsNullOrEmpty(requestToken.Token))
  {
    throw new Exception("The request token was null or empty");
  }

  Session[requestToken.Token] = requestToken;

  string callBackUrl = "http://localhost:" + HttpContext.Current.Request.Url.Port + "/Callback.aspx";

  string authorizationUrl = session.GetUserAuthorizationUrlForToken(requestToken, callBackUrl);

  Response.Redirect(authorizationUrl, true);
}

Bien que je ne sois pas sûr que cela ait à voir avec la configuration des points de terminaison de service, je suis en train d'exécuter le projet consommateur à partir de VS2008 et d'héberger le service sur IIS. S'il vous plaît des conseils.

Travailler maintenant. L’erreur était due à la page RequestToken.aspx dans OAuthChannel n’héritant pas de la classe correcte derrière lorsque le site consommateur faisait une demande pour un jeton qui entraînait une erreur de serveur interne côté ServiceProvider.
